Speciiication of Letters Patent.

Patented Jah'. 7, 1908.

Application filed February 7.1907. Serial No. 356,227.

To all 'whom it Imdp' concern:

B e it known that l', WlLLiAM ll. Waoxlcn, a cltizen of the United States, residing at Hebron, in the county ol' Thayer and Stato ot Nebraska, have invented a new and nscl'ul lncubator-lleatcr, of which the l'ollowing is a specification.

his invention relates to boilers for use in i connection with hot water heating systems in incubators or the like.

The object of the invention is to provide a boiler which -is of sim le and inexpensive construction and which) willdistribut'e the products of combustion from a lamp or other eater in such a thorough manner as to quickly raise the temperature of the water 'within the boiler and establish a circulation throu hthe system.

Wit ythese and other objects in View the invention consists of certain novel features of construction and combinations of parts which will be hereinafter more fully del scribed andpointed out in the claims.

ln' the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a longitudinal section through the device; and Fig. 2 is a transverse sectlon. therethrough on line :zc-a,

Figi. 1. eferring to the iigures by characters of reference,' 1 is a water receptacle preferabl rectanular in form and having one end wa l formed by 'a chimney 2 adapted to be placed above the lamp 3 or other device used for heating the water.v A damper L#l is arranged at the upper end `of the chimney for the purpose of control ing the discharwe of hot gases therefrom. Extending from tie chimney is i through the bottom of said receptacle. This ue is in contact with 'the inner face'of onev an L-shaped flue 5 which is disposed entirely Within the receptacle l and opens downward lwall ofthe receptacle so that it becomes imossible for water to circulate between the ue'and that Wall ofthe receptacle with whichr it contacts. A jacket '6 is arranged upon one end and one side of the receptacle and the upper end of this jacket is open while the lower end is normally closed b means oi' a slide 7. An outlet pipe 8 exten s from the y up er portion of-one side of the receptacle lan an inlet ipe 9 extends into the same side at a point bellow the flue 5. A filling o enin(T lOis formed in the top ot the receptac e and is normally closed by means of a cap 11.

the products ol' combustion will escapo di?` roctly through the upper or outlet end ol the chimney. ,By closing this damper, how over, tho hot gases will be dellected into the lluo 5 and will pass downward therethrough into the bottom portion ol' the jacket and will then spread over thi` bottom to `one side and end of the receptacle and escape from the top oi' the jacket. "he hot gases will l thus como into direct Contact with the two v ends, thc bottom and one side of the water lreceptacle and will also contact with the l walls ofthe flue 5.. A very large heating surface is thus produced and the water within the receptacle may bc quickly heated to a high temperature. .lhe circulation will of course beestablished outward through the upper pipe 8 and inward through the lower pipe 9, and as the flue 5 is connected directly to that wallofthe receptacle to' which the pipes 8 and 9 are secured it is obyious that the, waiter will 'be' prevented from passing*I directly from 'the pipe 9 tothe pipe 8 but will be deflectedllaterally by the` flue toward the opposite Wall of the receptacle before it can pass into the outlet pipe. The device is very simple and inexpensive in construction and the interior parts thereolI are all preferably constructed of co per or any otherv material whichv will readily conduct heat. By providing the pecnhar orran'ffement of jacket, flue, oto., practicallyr all of the heat may bo utilized for heating tho water. lt is of course mnlerstoglxthat bv manipulating tho damper lifthe heating rl feot may be increased or-din'iinishcd.

By forming the bottom ol' the jacket of u said slide to readily clean thc llue 5 and the 'interior of the jacket.

What is claimed is.'

A boiler lor heating systems comprising`a water receptacle having a normally closed inlet, outletand inlet pipes communicating with said receptacle and extending, respectively, l'rom the upper and lower portins ot' one wall thereof, a. chimney, said chimney and receptacle having one wall in common, an angular' llue incloscd within the receptacle and ,i disposed to direct`prmlncts of combustion j from lthe chimney; and through tho bottom ol" l the receptacle, said flue contacting throughout its length with said wall ol tho receptacle removable slide it is possible by removing lill between the inletl avniloutlct pipes to prevent l my own, l hay@` hereto ztlllxoal my Signatura direct flow of water from the inlet to the outg 1n thv prusonw ol' two nitiwssvs. let ipe, a jacket spaced from tllo receptacle y UJI AM H WAGNER an open at the top, and :L removable bottom 5 to said jacket disposed below the discharge y* Witnossos: v
